This is a new American Flyer 9 X 5 layout. It has three connected loops and the inner loop can be used as a reverse loop. The layout is light and portable. It has no legs and simply sits on the ping pong table. Engines run on DC. Engines are American Flyer, American Models, and S-Helper. The loops are isolated and the polarity of each loop is independently controlled by DPDT (center off) switches.
